Consider it...yes (half-heartedly). Actually do it....no if I know the exact machinations. If there's a full disclosure that I'm being brought in as a ringer, I'll refuse to participate. If I'm told otherwise and find out that I've been lied to, I'll play (begrudgingly and not with a lot of commitment) but it'll be a one time happening.
Fortune 500 Company: Hi Gemini, we've seen your resume on LinkedIn and the presentation you did at the SuperWorker conference. You have the skills that we are looking for to be a significant contributor to our new venture where we are trying to take market share from our Fortune 500 competitors. If you join us, we will pay you a large salary, stock options, bonuses, and we will pay for your relocation to our corporate headquarters.
Bridget, Crazy USTA Captain: Hi Gemini, I've seen that you played for Big Division 1 school, once had a world ranking of #179, and are undefeated playing as a 5.0 in USTA League for the past 5 years. I'm trying to assemble a 9.0 team in my hometown of Las Vegas that can win the USTA national mixed doubles title. You will be paired with Susanna, from Atlanta, who played the #1 spot for Florida State in the early 90's and somehow now has a 4.0C rating. Our Section has no residency requirements for team members and the local and Sectional tournament is played over one weekend next month. I will pay for your flights, meals, local transportation, and housing here in Las Vegas if you decide to play for our team.
In both scenarios, you are being asked to capitalize on your skills for a group of strangers in exchange for effort and remuneration. Does it matter that one is for a corporation and the other is for tennis? Is your answer really this?
"I will half-heartedly consider your offers, but if you are wanting me to actually use the skills that I'm being recruited for to attain a goal, I refuse to participate. And if I do decide to show up and you provide monetary compensation for my participation, I will only put in a begrudging effort with no commitment."
In my opinion, the issue here isn't really the players that agree to the compensation to come play in Las Vegas. It's a great offer! Why not take a free trip to Sin City to play tennis and have some fun trying to win a title for this lady?
The issue is really that this captain is so desperate to win that she is willing to shell out a large amount of money to make it happen. And maybe it's nothing to her because she's really wealthy. Several pro sports club owners have spent big money on their basketball, baseball, soccer, or football rosters to assemble the top players for a run at a title. It doesn't always work and it's a silly way to spend money, especially at the recreational level. As I've said, the little plastic trophy isn't worth it. However, if I was on the player side of this equation, I don't really see the problem if it's within the rules.
(Personally, I've played tennis on USTA teams all over the place. One year, I qualified for Sectionals on teams from three different districts. I don't remember ever being compensated, I just have a lot of friends who invited me onto their teams and I was happy to have the opportunity to play a lot, even if I had to travel quite a bit to do so.)
